摘要

利用MODIS 250M - NDVI长期预处理数据，对选定的流域研究点进行了热点分析(Getis - Ord Gi*)，观察了2001 - 2012年流域NDVI值的变化。对热点地区的总体空间变化进行了直观观测，并与拦河坝等集水结构的发生年份进行了对比。结果表明，集水设施建成后，小流域内NDVI值发生了变化。

Hot spot analysis using NDVI data for impact assessment of watershed development

Hot Spot Analysis (Getis - Ord Gi*) using long term pre-processed MODIS 250M - NDVI data for a selected watershed study site has been carried out for the period 2001 to 2012 to observe the changes in NDVI values. The overall spatial changes in the hot spots has been visually observed and compared with the incidence year of the water harvesting structures such as check dams. It is observed that after the development of water harvesting structures there is a change in the NDVI values within the sub watershed.
